The drivers side rear door will not unlock or open. When I hit the fob, the lock stem tries to come up to disengage the lock, but is jammed. I have read this has happened to others - probably something jammed/off track in the mechanism. I watched a video where a fella corrected the problem by manipulating a long thin screwdriver from the inside probing the locking mechanism, and popped whatever was out, back into place. This requires removing the inside door panel however. I'm not sure how to do that on my 2000 V40. Aside from one screw on the inside latch cover (see pic), there is nothing apparent. On the rear door that does open, I see two buttons that I suspect need to be removed in order to get the panel off. Unfortunately, they are completely inaccessible with the door closed. Any reccomendations on how I can get this panel off? Is it even possible on a 2000 V40 with a closed door?

Additionally, what is that weird black button on the jam? I hear it doing something, but I can't for the life of me determine its function.

Only visible screw when door is closed

These buttons are only accessible with the doofr open. Necessary for removing the panel?

What the heck does this button/swith do?

 

most door cards have a few screws (including the one behind the interior latch) and then have press clips. You should be able to slide in a flat blade to pop those apart. The card will then slid up off the top lip by the window. I've looked at this in the past and there's not a whole lot to it - there's a rod that goes from the interior handle to the latch and one that goes to the lock button. There is the power door lock actuator but nothing much there to lube up etc. You may need to replace the power lock mechanism as a unit. If I recall, the rubber "button" is just a weather seal and you can pop that out to access the lock mechanism. Check out a dealer web store to see if there's a diagram on the components.

 

Thanks! I'll proceed as you suggest this weekend and let you know how I fare

 

look for plastic circles, or squares covering hte screws like where u pull the door open and closed

 

I noticed them on some videos. I'm checking it out this weekend.

My main concern are those two buttons which are inaccessible with the closed door. I suspect there are screws behind those buttons. If that's the case, I'm out of luck. Thanks Richard. I'll let y;all know how I fare.

 

Success!! I was right about those buttons - there are screws behind them. It wasn't easy, but I was able to get them out despite limited access. Then it was a simple matter popping off the door panel. Some lucky probing and prodding from within popped whatever was out of line in the latch mechanism. It now works as designed. Thanks for the advice!
